A novel synthesis of 2-phenyl-4-[(triisopropylsilyl)methyl]quinazolinesfrom monosubstituted arenes has been developed. Treatment of N-phenylbenzamidines with 5-nitro-1-[(triisopropylsilyl)ethynyl]-1,2-benziodoxol-3(1H)-one and K2CO3 in the presence of a catalytic amount of CuBr in benzene gives 2-phenyl-4-[(triisopropylsilyl)methyl]quinazolines in moderate to good yields.
已开发了由单取代的芳烃合成2-苯基-4-[(三异丙基甲硅烷基)甲基]喹唑啉的新方法。在催化量的CuBr在苯中的存在下,用5-硝基-1-[(三异丙基甲硅烷基)乙炔基] -1,2-苯并恶多酚-3(1 H)-one和K 2 CO 3处理N-苯基苯甲m ,得到2 -苯基-4-[(三异丙基甲硅烷基)甲基]喹唑啉的产率中等至良好。
